WINDMILL-PUMP COUPLING.

SPECIFICATION forming part of Letters Patent No. 774,939, dated November 15, 1904.

Application filed July 8, 1903. Serial No. 164,718. (N model-i To all whom, it may concern:

Be it known that I, CARL WASHBURN DECKER, of Charles City, in the countyof Floyd and State of Iowa, have invented a new and useful Improvement in VVindmill-Pump Couplings, of which the following is a specification.

My invention is in the nature of a device designed to be attached to any ordinary windmill-pump, its object being to provide a convenient and efiicient means of coupling the hand-lever of the pump to the pump-rod, at the same time uncoupling the windmill-rod from the pump-rod,and vice versa. The means for attaining this object are embodied in a simple and compact device which is attached to a special form of windmill-rod, all the apparatus for coupling and uncoupling being contained in this pump-rod with .its attachments. It is intended that the device shall be made practical and extremely convenient in that this pump-rod may be placed in the pump, replacing the original pump-rod, and after attaching the device as hereinafter described the apparatus is ready to be used.

In the accompanying drawings, Figure l is a front view of the special pump-rod with its attachments. Fig. 2 is a side view of the same. Fig. 3 is a front view of the rod without its attachments; Fig.4, a side view of the same. Fig. 5 is a perspective view of the upper coupling-arm. Fig. dis a perspective view of the lower coupling-arm. Fig. 7 is a perspective view of a clevis-shaped loop or stirrup which is hung upon the pintle-pin of the hand-lever and cooperates with the lower coupling-lever shown in Fig. 6 to couple the hand-lever to the pump-rod. Fig. 8 is an enlarged perspective view of the buffer to be attached to the pump-rod, which buflter also serves as a guide for the upper coupling-arm and a means for attaching this coupling-arm to the pump-rod through a spring. Fig. 9 is a side view of a special form of pintle-pih and nut for the upper end of the hand-lever, said pin also serving as a means for suspending the stirrup shown in Fig. 7. Fig. 10 is a vertical longitudinal section of the windmill-rod slide. Fig.

11 is a perspective view of this slide. Fig. 12

is a side view of the entire device in position on an ordinary windmill-pump. Fig. 13 is a front View of the same. Figs. 14 and 15 are vertical longitudinal sections through the lower portion of the windmill-rod slide, the pump-rod, and upper coupling-lever, showing the device in position when uncoupled and coupled, respectively. Figs. 16 and 17 are detail views of a portion of the lower parts of the pump-rod and coupling-stirrup, showing the device as coupled and uncoupled, respectively.

' Referring to the drawings, Figs. 3 and i, this special pump-rod is made to conform in general outline to the shape of the ordinary pump-rod. At its upper end it has a special form of mortise A and A This mortise is formed by a rabbet on one side of a slot in the middle to receive a cross-head B, the upper end of the upper coupling-arm B, as shown in Fig. 5. The pump-rod has also an oblong opening at A constructed to receive the lug B of the upper coupling-arm B.

The above-mentioned opening A of this pump-rod corresponds in position to the position of the upper round hole in the ordinary windmill pump-rod. At A in the pump-rod therei's constructed a slot'extending from a pointA upwardly. Thepoint A corresponds in position to the position of the lower round opening in the ordinary windmill pump-rod. The slot extends upward to such a distance that when the rod is in position in the pump the pin of the hand-lever may pass through this slot and allow the upper end of the handlever to be at a position just below the guide of the pump-head when the rod A is at its lowest point of stroke while being carried by the windmill-rod slide.

A is a lateral enlargement of the slot A at its lower extremity, so designed that the middle portion of the stirrup D when held against the side X of this enlargement will couple the hand-lever to the pump-rod. V

A is a recess in thepump-rod on its side shown in Fig. i and extending from the front edge 3/ to the slot At .taching the spring E.

A is a notch in the edge y of the pumproc.

A is a half-round depression in the side of the pump-rod opposite to the side shown in Fig. 4:, which depression is located at ashort distance below the lower end of slot A and is intended to provide a means for attaching the buffer F by means of a bolt and nut to said pump-rod.

The lower end of B, as shown in Fig. 5, has an inclined plane at B which is used to move this lower end B out from the rod A by means of the stirrup D, throwing B out of connection with the windmill-rod slide, as described later. The extreme lower end of B is bent in a direction opposite to the bend B and has a hole B", serving as a means for at- (Shown in Figs. 1 and 2.)

The lower coupling-arm C, Fig. 6, has at its upper end a round hole C, providing a means of pivotally attaching it to the pumprod by means of a small set-screw C At its lower end the arm C has a hook C At C there is an upward extension of this lower end of arm G in a direction parallel therewith. This extension is designed to rest on pump-rod A at A and constitutes a spring to force arm C away from the edge 1 of the pump-rod.

F, Fig. 8, is the buffer, which when attached to pump-rod A, if the rod is allowed to drop, rests on the spring l-l, mounted on the pump-head. The buffer F has at-F two arms extending in a direction at right angles to the pump-rod A, as shown in Figs. 1 and 2, serving as a guide for the lower end of arm B. At F there is a small shoulder, with a hole adapted to receive the end of the spring E, the other end of which is attached to arm B at B.

Gr, Fig. 9, is a pin adapted to fit loosely in any ordinary pump-handle, having at G a notch on each side. This portion G of pin G is intended to rest in the slot A in pump-rod A. This pin has a special nut Gr and a split key G, adapted to pass through the hole Gr in the pin and engage the depressions in the rim of nut G allowing a limited adjustment of position of nut Gr on pin G sufficient to adjust pin G and stirrup D to differences in the width of the upper end of different hand-levers.

Referring to Fig. 10, l is a grooved plate, whose grooves are adapted to engage corresponding grooves on the surface of the windmill-rod slide I. These grooves are in a direction at right angles to the greatest length of the piece. At 1 there are holes adapted to receive bolts which pass through a slot 1 in slide 1 and then through the lower end of the windmill-rod. These bolts,w'ith suitable nuts, connect the parts 1 and l firmly to the millrod; but if the nuts on bolts are loosened sufdisengaged the part I may be raised or lowered a considerable distance by reason of the slot 1 after which the nuts may be again tightened to reconnect the parts.

At 1' in slide I there is a beveled mortise, which is adapted to engage the lug B in arm B. At 1 there is a recess, also adapted to engage the lug B just mentioned. As shown in Fig. 11, the part I is channeled longitudinally to slide on the rod A and has at its lower end two parallel outwardly-projecting lips 1, serving to keep arm B in position when the apparatus is in use.

The method of applying my devices is as follows: Referring to Figs. 12 and 13, the numerals 1, 2, and 3 represent the pumphead, lever-support, and hand-lever, respectively, of an ordinary windmill-pump, and 4 is the windmill-rod of an ordinary pumpingwindmill. 1f now it is desired to place in posit-ion the attachments described, the pumprod originally in the pump having been removed by uncoupling below the pump-head and sliding up out of guide .2, the rod accompanying this device is passed through the guide .2 from above and through the buffer F and spring H and then through the lower guide in the pump-head. My rod is then coupled below pump-head to the piston-rod of the pump. The lower coupling-arm C is next, by means of the set-screw C attached to the pump-rod A at A". Rod A now being forced down to its lowest position, the pintle-pin G is passed through one arm of stirrup D, D having first been passed through the slot A in the pump-rod, so that one arm is on each side of the rod. Pin G is then passed on through the hole in left side of the upper end of hand -lever, said hand-lever having been first brought into position embracing the pump-rod. The pin Gr is passed on through the slot A in the pumprod and through the hole in the opposite side of upper end of hand-lever and through hole in other arm of the stirrup D.' The nut G and the pin G may now be placed in position, the pin Gr holding the hand-lever in position embracing pump-rod A and also the stirrup D in position embracing the hand-lever, with its lower middle part passing through slot A in the rod A just below the upper end of hand-lever. By means of washers w, placed between stirrup D and the upper end of the hand-lever on either side, as in Fig. 13, the parts D and G can be made to accommodate different sizes of hand-lever. The pump-rod A being in position, the cross-head B of upper coupling-arm B is made to engage rod A at A and A and lug B is passed into the hole A of said rod. The arm B now being in position attached to rod A, the spring E, by means of the holes F in buffer F and B" in arm B, is attached to said parts F and B. Slide 1 is now attached to the windmill-rod 4 by means of plate 1, with its bolts and nuts,

ficiently to allow the grooves on 1 and I to be l first having been passed down over the upperend of rod A, embracing A and the two flat surfaces of'B. It will be noticed from the above that only a wrench and screw-d river are required to attach this device to the pump, making it extremely convenient.

Operation: The operation of the device is as follows: In Fig. 12 the hand-lever of the pump is shown in a position somewhat below the upper limit of stroke of its upper end, the lower couplings C and D being coupled to the pump-rod A and the upper coupling B being uncoupled from the slide 1, as shown in Figs. 16 and 14:, respectively. If now the hand-lever be moved so that its upper end moves still farther upward, it will carry with it the parts G and D and by means of them the pump-rod A. As the upper end of handlever approaches the guide .2 the shoulder of C at C (see Figs. 6 and 12) will come in contact with the inner surface of the guide 2 and the lower end of C will'be forced toward the backedge of rod A, carrying lower part of stirrup D from the side 00, Fig. 4, of lower part of slot A at A to the opposite side or edge of the slot. The relative position of the parts are now shown in Fig. 17, with stirrup D uncoupled from rod A, which latter is now free to either remain stationary or drop by its weight and that of the water in the pump, so that if the hand-lever is moved still farther in the same direction stirrup D, the arm of which has pressed out the arm B at B moves up and out of contact with the point B allowing coupling-arm B to move toward rod A from the tension of spring E, causing the lug B to pass through the hole A in rod A and engage the mortise I in slide I if I registers with B If I is at such a position that I does not register with B arm B being acted upon by spring E tends to force lug B through opening A in rod A and engage I in I as soon as I reaches such a position that I does register with B In the construction of slide I it is formed with a beveled lower end at I. The object of this is to allow this slide I to slide down over the lug B of arm B when B extends through A and projects from the surface of rod A without damage or jar to the lug B If the adjustment of length of stroke of the windmill-rod and the position of the slide on the rod is such that when the pump-rod is released by the hand-lever at highest point of stroke of pump-rod the lug B is left at a point higher than the highest point reached by recess 1 in I, the beveled recess I will engage lug B of arm B as slide I moves downward, forcing rod A, by means of arm B, down to a point where B is below the highest point reached by recess 1 so that B must register with and engage I upon the next upward stroke of slide I when moved by the windmill-rod. If now, the hand-lever being uncoupled from the pump-rod A, itis desired to couple the hand-lever to rod A and uncouple the windmill -rod, the lower end of the hand lever is raised and the upper end is thereby lowered. The arm of stirrup D which is on the side next to arm B (as soon as upper end of hand-lever is carried far enough downward)engages the inclined surface B of arm B, and a continuance of this motion causes the lower end of arm B to be forced away from rod A, causing lug B to be withdrawn from recess I in slide I, thus uncoupling the windmill-rod from rod A. A continuance of this motion of the upper end of handlever causes stirrup D to move downward in slot A until the inclined face of the hook C at the lower end of lower coupling-arm C is reached, when arm C will be forced toward back edge of rod A until stirrup D registers with the opposite notched side A, when stirrup D, by means of the spring G pressing on the front edge of rod A, will cause stirrup D to engage the notch A, so that the hand-lever is now coupled to the pump-rod A. This coupling cannot fail to be made, as rod A, if free to move, must be prevented from dropping too far by the buffer F and the spring H.

It will be noticed from the above-described operation of the device that it is impossible for the windmill-rod and hand-lever to be coupled to the pump-rod at the same time, as from the construction of the parts one coupling is entirely disconnected from the pumprod before the other coupling is connected to the pump-rod, and vice versa. This obviates accidents to the device and to those using it, which is a valuable feature.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a windmill-pumpcoupling, the combination of a pump-rod having at its upper end a rabbet A and slot A and a lockingopening A below, the upper coupling-arm B having a cross-head B at its upper end fitting the slot and rabbet at the upper end of the pump-rod and a locking-lug B adapted to engage the opening A the windmill-slide having locking-recess I also adapted to be engaged by said lug, a hand-lever and means for enabling it to operate upon the upper coupling arm, substantially as shown and described.
